Summary
serve-u
hosting isp business
Netnames that spell an address range out in words, and a function split written in two languages.
What it's used for
- A small German hosting and network operator. 2,048 addresses across five IPv4 prefixes, one IPv6 prefix, and 90 observed BGP neighbours.
Notable
- Netnames are
DE-SERVE-U-20180108,KIEZ-70-141,KIEZ-73-to-92,FMT32-CoreandFMT32-Kunden. - Three blocks are registered to a named individual and a separate network operations contact.
- The IPv6 announcement is a
/29, far larger than the IPv4 footprint. - One of 15 sampled addresses returned a name:
serve-u-on-the-road.FMT32.NET.
Interesting
KIEZ-73-to-92writes a range using the English wordtoinside an identifier, where every other netname in this range uses hyphens or nothing. It reads as a note to a human rather than a label for a system, which is what netnames actually are: free text nobody parses.FMT32-CoreandFMT32-Kundensplit infrastructure from customer space using an English word and a German one in the same pair. Both were obvious to whoever wrote them, and neither is obvious together.- Ninety BGP neighbours against 2,048 addresses is an operator that peers far more widely than its own address count would suggest. The interesting number here is the peering, not the space.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,772 prefixes, as published 2026-10-15. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
